[2023-11-26 00:09:14] <Lucifer_arma> jeez, how much is a quid worth these days?  That's got $20 shipping on top of it.  I could actually get a raspberry pi 3b for roughly the same price and it would probably do the job, too.  I was considering going that route to build a file server

[2023-11-26 00:11:08] <Lucifer_arma> I may look around some more, but it's not a high priority right now.  There's also a school district surplus store not far from me.  That's probably a good place to get a web server and file server, since they don't need much (although I imagine a file server would benefit from a shitload of ram)

[2023-11-26 08:47:55] <armagetron-bridge> 08discord:delinquent| I may have exaggerated a little, but I suspect if you have a little hunt for them you'll find them at similar prices as I did.

[2023-11-26 08:47:55] <armagetronbridge> 08discord:delinquent| As for a file server, kinda. Realistically it's a balance between memory (and properly balanced memory at that) and cpu performance. With the bandwidth of modern storage, you can find surprisingly quickly that the overheads of oh-so-many drives in raid overwhelm a processor in short order.

[2023-11-26 08:47:56] <armagetronbridge> 08discord:delinquent| That said, if you're on a budget, I wouldn't be so concerned - a cheapish dual or quad core machine with 8gb of memory will do just fine with truenas, xigmanas, unraid, fugu, or whatever other network storage solution you go with

[2023-11-26 22:36:32] <Lucifer_arma> well, the reason to prefer, say, a raspberry pi 4 is because later, when I upgrade the fileserver, the pi 4 becomes a worker node

[2023-11-26 22:37:22] <Lucifer_arma> it's 4 cores, and that can help network share performance, even with only 4-8GB.  The pi 3 is similar, but it's the older ARM version, so even though it's roughly the same clock speed as the pi 4, it's significantly slower.

[2023-11-26 22:37:43] <Lucifer_arma> but the pi 3 has the pseudo-gigabit ethernet issue :)

[2023-11-26 22:38:28] <Lucifer_arma> I'm not in a hurry to do the fileserver, though.  The scheduler needs to be on the same machine as the rpc server that I wrote, and the web server can be on either that machine or the fileserver.  Either is fine.

[2023-11-26 22:39:07] <Lucifer_arma> right now, the database is the fileserver as well, but it's only serving a shared directory for the cluster.  The fileserver in its final form will serve OSes for netbooting workers.

[2023-11-26 22:39:50] <Lucifer_arma> it might also serve as the syslog daemon for the entire cluster

[2023-11-26 22:40:42] <Lucifer_arma> but that's waaaaay down the road.  Right now, the question is "Do I buy another worker node, or a support node?" where support nodes are things like fileserver, webserver, database server, etc.  And I think the answer is "worker node", and that's a pi 4.

[2023-11-26 22:40:54] <Lucifer_arma> since the pi 5 came out, I'm watching pi 4 prices hoping they'll drop quite a bit.

[2023-11-26 22:41:52] <Lucifer_arma> I have one more slot available in my cluster case, and three empty pi 4 cases.  So if I make them all worker nodes, I currently have the cases for 7 in total.  I'll still need power supplies, but if I can find a single power supply for the cluster case (which takes four), then I'll have enough power supplies, too.

[2023-11-26 22:42:12] <Lucifer_arma> I can probably use the current fileserver as the netboot server.

[2023-11-26 22:42:42] <Lucifer_arma> SO now that I've typed this all out, I think the thing I should be looking for is a power supply that'll power 4 raspberry pi 4's.  That's the best thing to add to the cluster next.
